Why does production and test environments have to be similar?

Testing Environment

Unit testing can be completed in a virtual environment. It should conduct product performance testing in a physical environment with hardware and software that is identical to the production environment.

The testing environment is used to measure performance characteristics such as maximum sustainable input and maximum sustainable tracking output of the solution. It should therefore match the physical production environment as closely as possible.

Production Environment

The production environment is the "live" environment that will host the running software solution. The production environment is the final endpoint in the release management process and should only host applications that have previously undergone development, unit testing, load testing, and staging in the other environments. Thorough unit testing, load testing, and staging beforehand will help ensure maximum performance and uptime for the software application in the production environment.

What happens in requirement analysis phase in SDLC?

Image
For any  software development life cycle  (SDLC), the requirement phase is the first step toward unambiguity. It is an essential step because it reverberates with acceptance tests which are crucial for the end user acceptance. Here is the complete process of the requirement analysis and gathering phase of SDLC – Requirement gathering Also known as elicitation, software development requirements gathering is followed by an analysis of the needs so that the technology experts shall go for feasibility tests and may alter some objectives to convert the thoughts into a real product. The gathering technique involves precise research on what customers need. Nevertheless, it is not possible to put a survey questionnaire to each customer and get feedback; hence, the requirement for product, tool, or objectives is asked to the stakeholders who influence the product or who are well acquainted with the end users. The stakeholders could be software quality engineers or at times even...

What are the drawbacks in waterfall software development mode?

  What is the Waterfall Method? The Waterfall Model is a linear or sequential approach to project management and works based on fixed dates, requirements, and outcomes. Teams do not require consistent communication and, unless specific integrations are required, can be self-contained. Team members can also work independently and are often required to provide status reports somewhat less frequently (when compared to an agile approach). A typical Waterfall project is chronological and is made up of the following phases: Requirements Design Implementation Verification Maintenance Disadvantages of the Waterfall Model 1 . The waterfall model doesn’t support making changes. 2. It can invalidate the work you’ve previously accomplished. 3. This method excludes end-users and clients. 4. It delays testing until after the completion of the project. 5. The waterfall model can promote longer delivery times. 6. It typically works better for small projects. 7. Working m...
